Starlight Integrated Paracorr System (SIPS) is a Paracorr Type 2 built into a Feather Touch focuser. (Also available from them as an add-on if you already have a Feather Touch focuser.) Amateur telescope builders designing a fast Newtonian should consider including a SIPS in their design. The image below contains dimensions sufficient for planning the installation on a new or existing telescope. Contact Starlight Instruments for details and pricing.
